WINDOW BLIND OR SHUTTER.

SPECIFICATION forming part Of Letters Patent N0. 422,068, dated.February 25, 1890.

Application filed November 19, 1889- Sen'al No. 330,864. (No model.)

T all whom t may concern:

Be it known that I, JOSEPH CABUS, of the city and county of New York, inthe State ot' New York, have invented a certain new and usefulImprovement in Vindow Blinds or Shutters, of which the following is aspeciiication.

I will describe in detail a window-blind einbodying my improvement, andthen point out the novel features in a claim.

InA the accompanying drawings, Figure l is a face view of a window-blindembodying my improvement. Fig. 2 is an end view of the same, one of thesides of the frame being removed and showing the slats in a closedposition. Fig. 3 is a View similar to Fig. 2,' but showing' the slats ina wholly-open position. Fig. 4 is a view simi-lar to Figs. 2 and 3, butshowing the slats in a closed position, the converse of that shown inFig. 2. Fig. 5 is a crosssection taken on the line 0c Fig. l. Fig. G isa detail view on an enlarged scale and partly in section, the sectionbeing taken on `the line y y, Fig. l.

Similar letters of reference designate corresponding parts in all thefigures. i

The frame of the blind consists of upper cross-pieces A, and side 'orend pieces A A2. The cross-pieces A. of the frame are provided in theexample shown with dowel-heads a, as shown more clearly in dottedoutline in Fig.

l, which dovrei-heads extend into suitable dowels in the side or endpiece A. lYhen thus secured together, screws may also be employed topermanently prevent the disconnection of the parts. Secured to the inneredges of the portions A A A2 of the frame is a bead a. Such beadingconstitutes in effect a portion of the frame. Adjacent to the portion Aof the frame said beading is provided With alongitudinal groove aasshown more clearly in Figs. 2, 3, 4, and 5.

B designates slats of which there may be any desired number. These slatsare pivoted at both their ends in the side portions of the beading a.Theportions of the pivots of said slats which extend into the groove a2have rigidly secured to them cranks O. Fach of the cranks C is connectedto alongitudin allyL movable bar D by-a loose connection. It will bereadily seen that when by this arrange ment a longitudinal movement isimparted to the bar the latter will, through the operation of the cranksO, cause the rocking of the slats upon theirpivots to open or close saidslats to any desired extent and in either of two directions.

I have shown the slats as closed in one direction in Fig. 2 and in theother direction in Fig. 4. In the former figure the bar is broughtdownwardly to close the slats and in the latter it is elevated.

I have shown means for imparting longitudinal movement to the bar D,consisting of a pinion E, which pinion bears upon one side a slottedlink c, engaging a pin e', shown as forming part of one of the cranks C.Said pinion is j ournaled upon a stud c2, extending from a plate F',secured upon the beading a. The plate F is secured to the beading, asshown, by screws and incloses one side of a recess formed in thebeading, in which recess are arranged a rack e3 and a portion of thepinion E. Rotary motion is imparted to the pinion E by means of the racke3, which rack has connected to it a hand-piece e4, extending atapproximate right angles from said rack and into a recess c5, formed inaplate F, which plate is secured upon the portion A of the frame. Therecess c5 is of such depth thatthe hand-piece e* may be grasped by handand be moved up and down within the recess c5. The plate F, upon itsside nearer the plate F, is provided with a vertical slot e" to admit ofthe passage ofthe hand-piece through it. Such movement of the hand-piececauses a longitudinal movement of the rack, which imparts a rotarymotion ofthe pinion through which a longitudinal movement is given tothe bar, whereby the slats will be moved in different positions.

It is to be understood that in the present example ot my improvement theplate is sunk into the portion A of the frame, so that the plate andthehand-piece e4 will be flush or substantially flush with the face of theportion A of the frame. This admits of the portion A being hinged to thewindow-frame, and no obstruction will be offered by the plate F or thehandpiece e4 in the complete closing of the blind or Window.

It will be observed that by my improvement IOO all the mechanism foi1operating the slats except the hand-piece e4 is Wholly concealed, and itwill also be seen that if any accident should happen to the mechanismfoi1 operating the slats it is only necessary to remove the portion A ofthe frame in order to bring all said mechanism into View.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a frame, of slats pivoted in said frame, a movablebar having a crank-connection With all said slats, a pinion havingaloose connection with said bar, a rack engaging said pinion, and ahand-piece substantially flush with the face of said frame, saidhand-piece, rack, and pinion being adapted to impart longitudinalmovement to said bar in order to rock said slats into differentpositions, all said mechanism, except a portion of the hand-piece, beingwholly inclosed 2o Within said frame, substantially as specified.
